Research progress on ferroptosis regulated by glycolysis-fatty acid metabolism in metabolic diseases / 药学学报

In metabolic diseases, the accumulation of reactive oxygen species and oxidative stress are closely associated with ferroptosis. As a key regulatory factor, the imbalance between glycolysis and fatty acid metabolism can participate in ferroptosis directly or indirectly, thereby regulating the occurrence and development of various metabolic diseases. The essence of ferroptosis is a new regulatory cell death mode, which is caused by the excessive accumulation of iron-dependent lipid peroxide. It is closely related to glycolysis and fatty acid metabolism, which plays an important role in metabolic diseases. This regulatory cell death mode is significantly distinguished from other programmed cell death modes and has unique changes in cell morphology, symbolic characteristics and mechanisms. This paper first illustrates the main mechanism of glycolysis and fatty acid metabolism imbalance in the occurrence of ferroptosis, then reviews the research progress of ferroptosis in tumor, diabetes, rheumatoid arthritis and other metabolic diseases, and finally reveals the internal connection between glycolysis-fatty acid metabolism imbalance and ferroptosis, as well as its impacts on metabolic diseases, which provide new strategies for the prevention and treatment of metabolic diseases.

Methcathinone Increases Visually-evoked Neuronal Activity and Enhances Sensory Processing Efficiency in Mice / 神经科学通报·英文版

Methcathinone (MCAT) belongs to the designer drugs called synthetic cathinones, which are abused worldwide for recreational purposes. It has strong stimulant effects, including enhanced euphoria, sensation, alertness, and empathy. However, little is known about how MCAT modulates neuronal activity in vivo. Here, we evaluated the effect of MCAT on neuronal activity with a series of functional approaches. C-Fos immunostaining showed that MCAT increased the number of activated neurons by 6-fold, especially in sensory and motor cortices, striatum, and midbrain motor nuclei. In vivo single-unit recording and two-photon Ca2+ imaging revealed that a large proportion of neurons increased spiking activity upon MCAT administration. Notably, MCAT induced a strong de-correlation of population activity and increased trial-to-trial reliability, specifically during a natural movie stimulus. It improved the information-processing efficiency by enhancing the single-neuron coding capacity, suggesting a cortical network mechanism of the enhanced perception produced by psychoactive stimulants.

Anthelmintics nitazoxanide protects against experimental hyperlipidemia and hepatic steatosis in hamsters and mice

Lipid metabolism disorders contribute to hyperlipidemia and hepatic steatosis. It is ideal to develop drugs simultaneous improving both hyperlipidemia and hepatic steatosis. Nitazoxanide is an FDA-approved oral antiprotozoal drug with excellent pharmacokinetic and safety profile. We found that nitazoxanide and its metabolite tizoxanide induced mild mitochondrial uncoupling and subsequently activated AMPK in HepG2 cells. Gavage administration of nitazoxanide inhibited high-fat diet (HFD)-induced increases of liver weight, blood and liver lipids, and ameliorated HFD-induced renal lipid accumulation in hamsters. Nitazoxanide significantly improved HFD-induced histopathologic changes of hamster livers. In the hamsters with pre-existing hyperlipidemia and hepatic steatosis, nitazoxanide also showed therapeutic effect. Gavage administration of nitazoxanide improved HFD-induced hepatic steatosis in C57BL/6J mice and western diet (WD)-induced hepatic steatosis in Apoe -/- mice. The present study suggests that repurposing nitazoxanide as a drug for hyperlipidemia and hepatic steatosis treatment is promising.

Effect of Pembrolizumab on T Lymphocyte Subsets in Patients with Advanced Non-small Cell Lung Cancer and Its Therapeutic Effect / 中国肺癌杂志

BACKGROUND@#The aim of this study is to investigate the changes of peripheral blood lymphocyte subsets before and after treatment with pembrolizumab for non-small cell lung cancer and its clinical significance.@*METHODS@#A total of 32 patients with non-small cell lung cancer who received pembrolizumab treatment in The Affiliated Hospital of Qingdao University and Weifang People's Hospital of Shandong Province from January 2015 to December 2020 were selected as the observation group, and 30 healthy people during the same period were selected as the control group. Before treatment and in cycles 1, 2 and 4 after treatment, fluid cytometry was used to detect changes in the levels of lymphocyte subsets in the peripheral blood of patients.@*RESULTS@#The CD3⁺, CD4⁺, CD4⁺/CD8⁺ indexes of patients with non-small cell lung cancer before the treatment were significantly lower than those in the control group (P0.05), and the CD8⁺ index was slightly lower than before the treatment (P0.05). At the same time, this article shows through analysis that the expression of programmed cell death ligand 1 (PD-L1) and pathological types have no obvious influence on the effect of immunotherapy. Multi-factor analysis shows that it is more meaningful to observe the changes of CD3⁺, CD4⁺ and CD8⁺ at the same time to predict the effect of immunotherapy.@*CONCLUSIONS@#Pembrolizumab can regulate the changes of T lymphocyte subsets in patients with non-small cell lung cancer, improve the immune status of the patients, and there is no obvious adverse reaction. At the same time, monitoring the changes of lymphocyte subsets during treatment can predict the effect of immunotherapy.

Genetic Profile of Young Chinese Patients with Lung Adenocarcinoma / 中国肺癌杂志

BACKGROUND@#Occurrence at a younger age has been demonstrated to be associated with a distinct biology in non-small cell lung cancer. However, genomics and clinical characteristics among younger patients with lung adenocarcinoma remain to be determined. Here we studied the potentially targetable genetic alterations by next-generation sequencing (NGS) assay in young Chinese patients with lung adenocarcinoma.@*METHODS@#Eighty-nine surgically resected lung adenocarcinoma tissue samples from patients aged less than 45 years were collected with informed consent from all patients. Targeted NGS assays were used to identify actionable genetic alterations in the cancer tissues. Additionally, the genomic and clinical pathologic characteristics of 95 patients with lung adenocarcinoma who received NGS testing over the same period were analyzed retrospectively.@*RESULTS@#The frequencies of targetable genetic alterations in 184 patients with lung adenocarcinoma were analyzed by defined age categories, which unveiled a distinctive molecular profile in the younger group, aged less than 45 years. Notably, higher frequency of anaplastic lymphoma kinase (ALK) and human epidermal growth factor receptor 2 (HER2) genetic alterations were associated with young age. However, a reverse trend was observed for kirsten rat sarcoma viral oncogene (KRAS), serine/threonine kinase 11 (STK11) and epidermal growth factor receptor (EGFR) exon 20 mutations, which were more frequently identified in the older group, aged more than 45 years. Furthermore, concurrent EGFR/tumor protein p53 (TP53) mutations were much more prevalent in the younger patients (81.6% vs 44.9%), which might have a poor response to treatment with EGFR-tyrosine kinase inhibitor (EGFR-TKI).@*CONCLUSIONS@#NGS assay revealed a distinctive genetic profile in younger patients with adenocarcinoma. High frequency of concurrent EGFR/TP53 mutations was found in the younger patients, which especially warranted personalized treatment in this population.

Efficiency analysis of health resources allocation in public Chinese medicine hospitals based on data envelopment analysis / 国际中医中药杂志

By the means of stratified sampling survey, six provinces were selected from three regions in China, and the Chinese medicine health resources were evaluated and analyzed by data envelopment analysis (DEA) method in six provinces. The Jiangsu, Guangdong and Guizhou Provinces are in the effective state of DEA, which has been fully utilized in the input-output of TCM health resources, and has reached the best input-output combination. The Anhui, Henan, Gansu Provinces are in an effective state of non-DEA, and the input of health resources has not been fully utilized and the optimal scale of output has not been achieved. There are regional differences in health resources of TCM in public hospitals, and there is still room for further economic development. We hope that TCM service system can interconnect and optimize the regional allocation of TCM resources.

Protective effect of acupuncture preconditioning on oxidative stress injury induced by myocardial ischemia-reperfusion injury in rats / 中国针灸

<p><b>OBJECTIVE</b>To observe the protective effect of acupuncture preconditioning at "Jiaji" (EX-B 2) on acute myocardial ischemia-reperfusion injury (MIRI) in the rats and explore the mechanism.</p><p><b>METHODS</b>Fifty Wistar rats were randomly divided into a control group, a model group, a Jiaji group, a Neiguan group and a Quchi group, 10 rats in each one. In the Jiaji group, the Neiguan group and the Quchi group, electroacupuncture was given for preconditioning at "Jiaji" T4~T5 (EX-B 2), "Neiguan" (PC 6) and "Quchi" (LI 11) for 7 days before modeling. In the control group and the model group, the regular feeding was given, without any acupuncture. At the end of acupuncture, except the control group, ligating the left anterior descending coronary artery (LAD) was adopted to duplicate MIRI models in the rest groups. Electrocardio-gram (ECG) was monitored and ST-segment shift was analyzed. HE staining method was adopted to observe the morphology of cardiac tissue in the rats of the groups. The transmission electron microscope was used to observe myocardial cell ultrastructure. WST-1 method was used to determine the activity of serum superoxide dismutase (SOD), TBA method was used to determine the content of serum malondialehyde (MDA) and the real-time fluorescent quantitative PCR method to determine the expressions of Nrf 2 in ischemic myocardial tissue and downstream HO-1 gene.</p><p><b>RESULTS</b>Compared with the control group, after LAD ligation, ST-segment was elevated and depressed in ECG apparently after reperfusion in the rest groups (all<0.05). The ST-segment elevation in the Jiaji group and the Neiguan group was less than that in the model group (both<0.05). Compared with the model group, SOD activity was increased apparently in the Jiaji group and the Neiguan group (both<0.05), and MDA content was reduced apparently (both<0.05). The effects in the Jiaji group were better than those in the Neiguan group (both<0.05). Pathologically, "Jiajia" (EX-B 2) and "Neiguan" (PC 6) all improved the morphology of cardiac tissue and cell ultrastructure. The effects in the Jiaji group were much more significant and the improvements in the Quchi group were not apparent. Compared with the control group, the expressions of Nrf 2 and HO-1 gene in myocardial tissue were down-regulated in the model group (both<0.05). Those were up-regulated apparently in the Jiaji group and the Neiguan group as compared with the model group (<0.05,<0.01). The up-regulation times of the expressions of Nrf 2 and HO-1 gene in the Jiajia group were the highest in comparison.</p><p><b>CONCLUSIONS</b>Acupuncture preconditioning at "Jiaji" (EX-B 2) has the protective effect on cardiac ischemia and reperfusion damage, which is probably relevant with the up-regulation of Nrf 2-ARE pathway expression, the activation of endogenous anti-oxidative pathway, the improvement of oxygen free radical scavenging capacity and the alleviation of lipid peroxide damage.</p>

Role and mechanism of action of fibroblast growth factor-21 in reducing triglyceride in nonalcoholic fatty liver disease / 中华肝脏病杂志

<p><b>OBJECTIVE</b>To investigate the role and mechanism of action of fibroblast growth factor-21 (FGF-21) in reducing triglyceride (TG) in the in vitro and in vivo models of nonalcoholic fatty liver disease (NAFLD).</p><p><b>METHODS</b>(1) A mixture of free fatty acids was used to establish a model of steatosis in L02 cells, and the cells were treated with various concentrations of FGF-21 or fenofibrate. Twenty-four hours later, oil red O staining was performed to observe the degree of steatosis, and intracellular TG content was determined. RT-PCR and Western blot were applied to measure the mRNA and protein expression of sterol regulatory element-binding protein-1c (SREBP-1c). (2) High-fat diet was used to establish a mouse model of steatosis, and these mice were intraperitoneally injected with FGF-21 or fenofibrate. Eight weeks later, whole blood and liver samples were collected, and HE staining was performed to observe steatosis. Meanwhile, the serum levels of TG, alanine aminotransferase (ALT), and aspartate aminotransferase (AST) were measured, and TG content in the liver was also measured. One-way analysis of variance was used for comparison of data between multiple groups, and the least significant difference t-test was used for comparison between any two groups.</p><p><b>RESULTS</b>(1) Compared with the control group, the model group showed significant steatosis, with significant increases in intracellular lipid droplets and TG content (t = -20.57, P < 0.01), while FGF-21 reduced the number of intracellular lipid droplets and TG content (F = 98.16, P < 0.01) in a dose-dependent manner. In addition, the model group had significantly increased mRNA and protein expression of SREBP-1c compared with the control group (t = -10.73 and -0.1006, both P < 0.01), while FGF-21 down-regulated the mRNA and protein expression of SREBP-1c (F = 161.35 and 36.72, both P < 0.01). (2) Compared with the mice in the control group, those in the model group showed significant steatosis and had significant increases in serum TG level and TG content in the liver (t = -18.84 and 15.71, both P < 0.01). FGF-21 relieved hepatic steatosis and reduced the serum TG level and TG content in the liver (t = 18.11 and 9.46, both P < 0.01). Moreover, FGF-21 reduced the serum levels of ALT and AST in NAFLD mice (t = 25.93 and 12.50, both P < 0.01).</p><p><b>CONCLUSION</b>FGF-21 can inhibit the synthesis of TG through suppressing the expression of SREBP-1c, which further confirms the potential therapeutic effect of FGF-21 in the treatment of NAFLD. This may provide new ideas for the treatment of NAFLD.</p>
